How to create inward curve with edge crease?
This face is an N-Gon which notoriously doesn't bode well with subdivision surface, and it is concave, meaning there is an interior angle &gt; 180°, which also can create artifacts.
By joining the 2 vertices with J or Vertex &gt; Connect Vertex Path and increasing the crease on the new edge, you will be able to make the subdivided mesh adhere more to the base mesh.

Although you now have a triangle to get rid of, but this is another topic :)
